Q. (a1)(b1)(c1) -(a-1)(b-1)(c-1) \newlineWhich of the following is equivalent to the given expression?\newlineChoose 11 answer:\newline(A) (1a)(b1)(1c) (1-a)(b-1)(1-c) \newline(B) (1a)(1b)(1c) (1-a)(1-b)(1-c) \newline(C) (a1)(1b)(1c) (a-1)(1-b)(1-c) \newline(D) (1a)(1b)(c1) (1-a)(1-b)(c-1)
  1. Given Expression: We are given the expression (a1)(b1)(c1) -(a-1)(b-1)(c-1) and we need to find an equivalent expression among the options provided.
  2. Distribute Negative Sign: Let's distribute the negative sign across the expression. This will change the sign of each term inside the parentheses.\newline(a1)(b1)(c1)=(1)(a1)(b1)(c1)- (a - 1)(b - 1)(c - 1) = (-1) \cdot (a - 1)(b - 1)(c - 1)
  3. Apply Negative Sign: Now, we apply the negative sign to each term inside the first set of parentheses.\newline(\(-1)\cdot(a1-1)(b1-1)(c1-1) = (11-a)(b1-1)(c1-1)
  4. Compare with Options: We can see that the expression \(1-a)(b1-1)(c1-1)\ is equivalent to the given expression. Now, let's compare this with the options provided.
  5. Option (A): Option (A) is \(1-a)(b1-1)(11-c)\, which is not equivalent to our expression because the sign of the last term c\(-1)\ is different.
  6. Option (B): Option (B) is \(1-a)(11-b)(11-c)\, which is not equivalent to our expression because the signs of the second and third terms are different.
  7. Option (C): Option (C) is a\(-1)(11-b)(11-c)\, which is not equivalent to our expression because the sign of the first term is different.
  8. Option (D): Option (D) is \(1-a)(11-b)(c1-1)\, which is not equivalent to our expression because the signs of the second and third terms are different.
  9. Correct Equivalent Expression: The correct equivalent expression is not listed among the options provided. Therefore, none of the options (A)(A), (B)(B), (C)(C), or (D)(D) are equivalent to the given expression (a1)(b1)(c1)- (a - 1)(b - 1)(c - 1).
